I would have rated this cruise a 3.5 overall. strong points being the destinations (fabulous) which were various, many and interesting, the staff (very trying their utmost and always available on Celebrity), the food at oceanview and at that extra charge Italian restaurant (cant already remember the name, but the food was awesome).
A special kudos to the Blu staff, overall excellent (better than the food which was ok).
The destinations were awesome but we enjoyed our time mainly when we took a private tour guide away from the cruise shore excursions (to the exception of Jeju Island, very nice).
beautiful city, lots to visit, nice mixt of Asia and Occidental modernism
beautiful city not too crowded and nice population. excellent food, plenty to visit but be careful as far away from the port.
